Abstract
Air pump tube, characterized in that it is made up of connections that are threaded inside the thread that forms the metallic coating inside which is covered by the conductive tube and this in turn by the outer metallic coating whose ends make butt in two flanges that present the connections and is joined to them by a weld, being able to build the tube with a single metallic coating, achieving the perfect union of the connections with metal stops, in the form of a cylindrical ring.
